I'm not sure what to do. It is quite obvious that the "Mayrina" with the lower hit chance is Auntie Ethel. If you cannot see it and the result is random, however it may just be an incentive for save scumming. I would leave it as it is, probably.
BTW I always kill Auntie Ethel. She is the only really evil creature in the game. Other than the Goblins, Drow, Duergar etc. she has no factual agenda and goals other than her pleasure with torturing and killing. I would throw out anybody from the party who showed the slightest doubt what to do with her. On the meta, I would delete the game from the harddrive if you had to support her. Mayrina on the other hand loves her husband. I can understand and always help her.
